Abstract

The present invention provides a load-indicating device for use with structural assemblies that have fastening components such as nuts and bolts. The load-indicating device comprising a washer having a tubular body defining a bore extending therethrough, the body comprising at least one hole extending at least partially through the body; and a probe configured to be disposed within the at least one hole and operable to provide an indication of the compression on the washer, such that, in use, the washer deflects to compress the hole against the probe when the load on the washer reaches a predetermined tension.
